Pollination Information for D.D. Blanchard Southern Magnolia

The D.D. Blanchard Southern Magnolia (Magnolia grandiflora 'D.D. Blanchard') is a flowering tree that produces large, fragrant, creamy white flowers. In order to produce fruit, the tree needs to be pollinated by insects.

Pollination Mechanisms:

The primary pollinators of the D.D. Blanchard Southern Magnolia are beetles, especially the tulip tree beetle (Agelastica alni), which is attracted to the magnolia's strong scent and large flowers. Bees and other insects also visit the flowers, but they are not as effective at pollinating the tree.

Pollination Requirements:

D.D. Blanchard Southern Magnolia is self-incompatible, which means it requires cross-pollination from another tree in order to produce viable fruit. The tree is also sensitive to cold temperatures and will not produce fruit in regions with harsh winters. Therefore, it is recommended to plant at least two magnolia trees to ensure successful pollination.

Blooming Time:

The D.D. Blanchard Southern Magnolia blooms from late spring to early summer, typically in May or June. The tree produces flowers for several weeks, allowing ample time for pollinators to visit the tree.

Fruit Production:

If successfully pollinated, the D.D. Blanchard Southern Magnolia will produce large and unique fruit that are cone-shaped and contain bright red seeds encased in a bright red pulp. The fruit ripens in late summer to early fall and can be used for decorative purposes or to grow new magnolia trees.

Pollination Tips:

• Plant two magnolia trees to ensure successful cross-pollination
• Select a planting location with plenty of sunlight and well-drained soil
• Avoid planting near buildings or structures that could block pollinators from accessing the tree
• Do not use pesticides or insecticides near the tree during blooming season
